Simplifying g2 + 20g + 46 = 0 Reorder the terms: 46 + 20g + g2 = 0 Solving 46 + 20g + g2 = 0 Solving for variable 'g'. Begin completing the square. Move the constant term to the right: Add '-46' to each side of the equation. 46 + 20g + -46 + g2 = 0 + -46 Reorder the terms: 46 + -46 + 20g + g2 = 0 + -46 Combine like terms: 46 + -46 = 0 0 + 20g + g2 = 0 + -46 20g + g2 = 0 + -46 Combine like terms: 0 + -46 = -46 20g + g2 = -46 The g term is 20g. Take half its coefficient (10). Square it (100) and add it to both sides. Add '100' to each side of the equation. 20g + 100 + g2 = -46 + 100 Reorder the terms: 100 + 20g + g2 = -46 + 100 Combine like terms: -46 + 100 = 54 100 + 20g + g2 = 54 Factor a perfect square on the left side: (g + 10)(g + 10) = 54 Calculate the square root of the right side: 7.348469228 Break this problem into two subproblems by setting (g + 10) equal to 7.348469228 and -7.348469228.Subproblem 1
g + 10 = 7.348469228 Simplifying g + 10 = 7.348469228 Reorder the terms: 10 + g = 7.348469228 Solving 10 + g = 7.348469228 Solving for variable 'g'. Move all terms containing g to the left, all other terms to the right. Add '-10' to each side of the equation. 10 + -10 + g = 7.348469228 + -10 Combine like terms: 10 + -10 = 0 0 + g = 7.348469228 + -10 g = 7.348469228 + -10 Combine like terms: 7.348469228 + -10 = -2.651530772 g = -2.651530772 Simplifying g = -2.651530772Subproblem 2
g + 10 = -7.348469228 Simplifying g + 10 = -7.348469228 Reorder the terms: 10 + g = -7.348469228 Solving 10 + g = -7.348469228 Solving for variable 'g'. Move all terms containing g to the left, all other terms to the right. Add '-10' to each side of the equation. 10 + -10 + g = -7.348469228 + -10 Combine like terms: 10 + -10 = 0 0 + g = -7.348469228 + -10 g = -7.348469228 + -10 Combine like terms: -7.348469228 + -10 = -17.348469228 g = -17.348469228 Simplifying g = -17.348469228Solution
The solution to the problem is based on the solutions from the subproblems. g = {-2.651530772, -17.348469228}
